What is the wife's role towards a husband who works in a usurious bank in the guarantees department? What should she do regarding the money he brings home? And what is better for her: to seek a job to cover household expenses or to care for her family and be patient?

The nature of the husband's department at the bank is not clear, and working in usurious banks is impermissible, regardless of the nature of the work. If what the husband does is merely a guarantee, or if a reputable scholar has issued a fatwa permitting this work, then he may follow that opinion. Otherwise, he is not permitted to remain in this job unless he cannot find another and is in need. In that case, he may remain for as long as the need persists, until he finds another job, and the wife is permitted to partake of his money. However, if he is not in distress, then the wife's partaking of his money is permissible if she is unable to earn and dispense with his money. But if she can earn, then it is not permissible for her to partake of his unlawful money. The husband is obligated to earn a lawful livelihood and to provide for his family.
